Google now have the ability to index spoken words on video, this new development has opened up a whole new spectrum for ecommerce websites in the way they work around the duplicate content penalty. The preferred method at present is for sites to incorporate robots.txt, although this blocking method works well, it defeats the object of having a large spread of items having the ability to rank highly in Google’s natural listings.
Google’s development is welcome news to website owners who now have the option of cataloging all their items on video, like a mini QVC. As long as particular interest is taken with the video transcript it will give uniqueness to each page, which in turn will prevent the use of robots.txt.
So far this method has not been expanded on, however I guess it will not be long before the concept is grasped.
